STRAW-STACKING MACHINE.

SPECIFICATION forming part of Letters Application filed October 1-2, 1883.

T 0 all whom it may concern.-

Be it known that I, JAMES BUCHANAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have-invented certain new and useful Improvements in Straw-Stacking Machines, of which the following is a specification. 4

My invention relates to improvements in straw-stacking machines; and the objects of my improvements are, first, to dispense with the endless apron and its running mechanism common to straw-staekers and use in its place a fan in connection with a telescoping dischargetube; secondly, to automatically turn the discharge-tube and so distribute the straw uni formly upon the stack; thirdly, to produce a lighter and cheaper machine, and one which tofore been produced. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the machine. Fig. 2 is a top view of the same; Fig. 3, a vertical cross-section through the machine on line :0 w on Fig. 1; Fig. 4, a horizontal section on a larger scale on line 3 3/ on Fig. 1; Fig. 5, detail drawings and sections through the discharge-tubes; Fig. 6, a vertical section through the first joint of the discharge -tubes on line 2 z on Fig.4, and Fig. 7 a vertical cross-section through the discharge-tube on line 10 w The same letters refer to the same or corresponding parts throughout the several views.

B is the receiver, into which the chaff and straw from the thrashing-machine are discharged. The fan I) in the lower part of the receiver B drives the chaff and straw out through the discharge-tubes O O 0, when operated by a belt directly or indirectly from the thrashing-machine or engine. The disated on the truck and frame A by flanges s s s or a flanged band overlapping the shoulder or ring G, to which the first joint 0 of the discharge-tubes is riveted, said ring Gresting on anti-friction balls or rollers g To the front of shoulder or ring G is secured the wire chain or rope K, which passes around at each side and to rear of tube 0, and through Patent No, 297,561, dated April 29, 1884.

the pulleys P and I? back upon the shaft I, in such a manner that when the rope is-winding up on one side of the shaft it unwinds on the\ other side, causing the discharge-tubes C G O to turn. The discharge-tube will turn in one direction until either of the arms m m shall have moved around to the center of the machine, when it will strike the arm j on the shifting-rod J and throw the belt 0 from one pulley to another, which will, by means of a crossed belt, reverse the motion of the shaft I and cause the discharge-tubes to move in the opposite direction until the arm m on the opposite side of the discharge-tube shall have moved around, and by striking the arm j on the shifting-rod J, thrown the belt 0 off from the pulley onto the one from which it came, and so on as long as the machine is operated. The discharge-tubes C G O are held in place with the pivot 6, over the center of and secured to the band E of the first or elbow joint, 0, by the braces D D D, and the joint 0 is stiffened and the band E braced onto shoulder or ring G by the braces 12 n. The tubes 0 O G are held together when drawn out by the iron bandsE E E, riveted to said tubes and formed in two parts, with flanges at the ends to receive the blocks R B, through which to bolt the bands together. Through the upper blocks R are holes to receive the wire rope F, which is secured to the last joint of the discharge-tubes and passes through the blocks R on each of the bands E and E, to the windlass F, for the purpose of supporting the tubes. To the lower 8 5 blocks B one end of the iron stays or rods L are secured to the front end of each joint 0, the other end of the rod passing through an opening in the block on the tube directly back of it, and secured to the block, when the tubes are drawn out, by a set-screw, Z,therods L L thus forming a -strong stay for the tubes when the same are drawn out for operation. When the machine is not in operation, the joints 0 O G are telescoped over the joint 0. The 5 machine is then ready for transportation.

To prepare the machine for work, the last one of the dischargejoints is drawn out, andthe rod L of the next joint is secured to the band E of the last joint by the set-screw Z. The other joints are drawn out and secured in the same manner. The fan I) in the receiver B is operated by a belt from the thrashingmachine, or from a pulley from the strawstacker. The discharge tubes are swung around, moving automatically from one side to the other, by the belt 0 from the thrashing'niachine passing overeither of the pulleys h" and h on the shaft H. The pulley h is firmly secured to the shaft II, also is the pulley h, while the double pulley h is loose on shaft H. 75- is an idler. The pulley h operates the pulley i on shaft I by a belt. Said pulley i is secured to shaft I; also is the pulley i, which is connected by a crossed belt to the loose double pulley h on shaft H.

To one side of the shaft I is secured the wire rope or chain K, which passes" through the stationary guide-pulley I at rear of tube G, around and to the front of the discharge-tube C, and is there secured to the ring or shoulder G. From there it passes around the other side of the discharge-tube 0, through the guide-pulley 1?, to the other side of the shaft I, being wound around the shaft I the reverse way from what it is at the other side, so that as it is wound from one side it is taken up on the other, until one of the arms m engages with army on the shifting-rod J, and shifts the belt What I claim, and desire to secure by Letters Patent, is-

1. In a straw-stacking machine, the combination of the receiver B, the fan b, the discharge-tubes O O O, ring or shoulder G, antifriction balls 9 g, the ropes K K, the shaft I, the arms m m, the shifting-rod J and arm j, the pulleys i i on shaft I, the pulleys h h and h on shaft H, and the driving-belt O, substantially asdesoribed, and for the purpose specified. v

2. In a straw-stacking machine, the combination of the receiver B, the fan b, the telescoping discharge-tubes C O O, the iron bands E E E, the blocks R R, the iron stays L L L, the set-screws Z Z Z, the braces n n, the shoulder G, and the flanges s s s, substantially as de scribed, and for the purpose specified.

3. In a straw-stacking machine, the combination of the receiver 13, the fan I), the telescoping discharge-tubes C O O, ring G, the iron bands E E E, the blocks R R, the wire rope F, the pivot c, and the braces D D D, substantially as described and specified.

In testimony whereof I liave signed my name to this specification in the presence of two subscribing witnesses.

JAMES BUCHANAN.
